To all 'whom 'it may concern.:

Be it known that I, GEORGE a citizen of the United States, residing atSouth Amboy. in the county of Middlesex and State of N ew Jersey, haveinvented new and useful Improvements in Car-Brakes, of which thefollowing is a specification.

S. CLAUER,

This invention relates to improvements in devices for causing=thepositive stoppage of vehicles, with special reference to types runningon track rails, where it is often desirable to cause the car to come toan instant halt, in order to prevent damage and injury to persons orthings in its pathway.

The principal object of the invention is to provide a device whereby theresults, as stated above, are effectually performed Without specialmanual exertion on part of the operator..

' Other objects are to provide such stopping means in forms that can beinstalled on cars as presently constructed, either when in the processof manufacture or ata later period. These objects are attained by thenovel construction and combination of parts hereafter described andshown in the accompanying drawings, forming a material part of thisspecification, and in which Figure l is a side elevation of a commontype o street car showing the application of the invention. Fig. 2 is anenlarged fragmental side view, showing in detail the construction of thebrake, and drawn to an enlarged scale. Fig. 3 is a partial sectional andend View, Fig. l is plan and sectional further enlarged scale, of a ingmechanism and take line 4-`4 of Fig. '5. Fig. 5 is a partial front vandsectional View of the same, the section being taken on line 5-5 of Fig.4;. Fig. 6 is a sectional View of a track rail and brake shoe, used withthe device, the section being taken on line 6-6 of Fig. 7. Fig. 7 is apartial side vieW of the same. Fig. 8 is a plan View of the contactingelements of the brake, indicating their normal position With referenceto the rails, and Fig; 9 is. a perview, drawn to a part of thebrakspective detail, showing the means by which the brake is attached tothe car.

Referring to the drawings, and more particularly to Fig. l thereof, anordinary type of car is indicated by the numeral 15, which may be drivenby any of .the usual means as steam, compressed air, electricity, etc.,land Specification of Letters 1atent. y

' cylinder 19,

substantially on Patented Apr. it, sem-.1 no. sacri.

provided with a cylinder 16, adapted to 4ceive compress-ed air from anyconveni source supplied by the motive power oi" the car.

A heavy steel plate 18 is rigidly secured below the car body, extendingfrom end te end thereof, and to this plate is attached by means of theiange 20, verse openings 2l being formed in the and also partiallythrought/he cylinder 3.9, .j

the openings acting as a guide-Way for rod 23, having an enlargedportion 2t, the upper and lower sides of Which formed with inclinedsurfaces in the manner `oi a wedge. The rod 23 may be connectedoperatively with a piston movable in, the cylinderA 16 or moved in anyother preferred manner. y

The cylinder 19 has formed transversely through its Walls at rightangles to the opening each other, and movable freely therein, is a pivotbar 27 held normally upward by reason of the coiled pull springs 23,secured at their upper ends to eyes 29, set in the plate 18, the lowerends being connected with rings 30, surrounding the bars 27 and held inplace by collars y3l'.

Centrally between' these collars, 'on the bars 27, are the rod ends 33engaging with the rods 35 which pass down into the cylinthereto, andterminating in a flanged disk or collar 38 which is' rigidly connectedWith the rod 35 by means of the hub 39. 4

rilhe cylinder 36 has an integrally formed head, l0 provided with anextension in which is secured the stub endioilY a rod e2, terminating atits lower opposite end in 'the tenon 44, pivotally engaged with thebrake carriers 45, to which are removably attached the brake shoes 46,which make contact with the `rails as indicated.

Connecting between the brake carriers are bars 47 by which thebrakingelements are held in relative rigid position, forming in effectthe base of'a 27 is the apex.

Interpesed between the flange 38 and bot tom of the cylinder 36 are aplurality of springs 48 adapted to exert ressure there` between so thatthe brake s ces may not make too rigid. Contact With the rails when thebar 23 is actuated by the admission 'of air to the cylinder 16,Iaflierelry the bar 2?,

'21, elongated slots 26, opposite tok ico terred embodiment with itslattached parts, are moved down, cansingthe brake shoes to impinge uponthe track rails and eect stoppage of the car.

When the rod 23 is moved in the opposite ,L 5 direction, the springs 28'drawthe bar 27 -upward allowing the car to proceed. rThus it will beseen that an effective de` i vice is provided which will bring the carto a stop by the combined 'edects of its own l0 'Weight applied throughthe wedge '24, but i materially eased by the action of the springs' 48so as to avoid any violent shock which would otherwise take place.

fi/While .i have shown and described a preo the brake apparatus, it isto be understood that modifications may be made therein relative to thescope of the appended claims.

What claim asnew and desire to obtain by Letters Patent is i. in abraking device for railway cars,

pairs di spaced brake elements adapted to 'make irictional contact withthe track rails cn each side of the car,connections between 25 theelements in each pair whereby they are held in rigid relation, otherconnections converging to a common central pivot, a verticallyslidablehead in which the pivot 1s mounted,`means for actuating said head, andmeans combined with said connections whereby said elements are'tensionallyapplied to the rails when" said rhead is depressed. l I

2. in al vehicle adapted to operate upon a track-way, the combinationwith a power source, of a rodoperable thereby, a plate secured at thebottom of the vehicle, a bracket on said plate, said bracket acting as asupporting guide for said rod, a .pair of rods pivotally and slidabl'yengaged in said bracket, said rods being divergently mounted, brakeshoes at the ends of 'said rods, means combined with the first named rodfor depressing' said second rods, and a resilient connecting meansinterposed between said second named rods and said brake shoes.

lin testimony` whereof I have signed my name to this specification.
